Floors climb up wrong

Having the same issue. Watch is new (got it last week) so no question of the baro hole getting clogged. I contacted Support on phone - not even an email to acknowledge their efforts, did a chat but the woman treated by like an idiot and kept repeating the same script over and over again despite me telling her that I have already dont those steps multiple times and the watch still does not count floors properly. I even a fitbit Sense on the same wrist registering all the floors but not Garmin. Have photos to prove that. Support is not helpful in resolving the issue. Very disappointed. My floors are 11 feet (1st floor to 2nd floor 11 feet and basement to first floor 11 feet. While using the activity "Floor Climb" the watch also shows the altitude and despite the change in altitude while going up and measuring the height 11 feet, the floor may not count!
They need to address this in the next firmware or software update. 
The rep telling me again and again to go  out in sub-zero temps was not helpful. I do have large french windows and the GPS signal is acquired just fine and the watch has been calibrated multiple times using GPS as well as manually entering the local elevation.

I can have the watch in my pocket and it counts floors climbed.  I don't think swinging arms or handrails are a significant factor.  It's mentioned in the FAQ, but this is emphasized "To earn credit, you must be moving forward and up "

I have found that going down into my basement and turning around and going right back up the stairs is the circumstance when it occasionally misses a climb.  However, if I stay in the basement for more than 30 seconds, it does count the climb.

Outdoors climbing stairs (like a bluff from a beach to the top) it never misses a climb.  Recording a walk with up/downs also works well for me.

Same Garmin Venu 3s 120 floors. Garmin counts only 103. Did calibration in the start

I have another Garmin venu 3 now. It is a little better than the previous one that I returned. 

I think the first one had hardware issue but the software issue  still remains. 

If the programmers have a little bit of insight, they will start assigning proper power to the relevant sensor during any activity. It should not take 7-10 seconds for the floor to register after I come up 1 floor. I have to hold my arm at the waist level for at least 7-10 seconds while it goes up 1 foot per second till it reaches 11 feet and then the floor registers. 

I calibrate it before activity many times using GPS. 

My suggestion to the programmers is that in their new update they allot some priority to the power of the barometer sensor and make the sensor real time. I don't care if I get a couple of days worth less battery as I charge it every weekend even if it has 25% left. To me, more important is measuring my floors as that is my main exercise routine. 

It is my thinking that (and I am not a programmer but just someone who likes to analyse things!) in order to get better battery life, they are reducing the power to the active sensor (in this case the barometer) which in turn has to be slow in registering the height climbed. 

They can take a lesson from Fitbit which is much much faster in counting the floors and distance climbed. As soon as I come up 1 floor, I see it on screen right away. The only time it messes up is during very bad weather with constantly changing pressure. 

Another thing they can do is give us a choice to choose the height of our floor. In USA is it not uncommon to have a 9 foot high floor. Just like there are options to measure your stride, there should be an option to manually input your floor height with default being 10 feet. 

I am talking about brand new Garmin Venu 3S that is not with baro hole clogged, did alsow get new from seller same result it is not giving the right floor count. If I calibrate before it is a little bitt better but the baromat seem so slow that if I do not stopp and walk on every floor before going on it is mabe counting 60% of the real floors that I am walking.
It is simply not working right.
Dont give me FAQ about cleaning baromat hole. That is not the problem. The problem is that it is unable to count right when I am walking upp and down 4 floors again and again and in the end if I walk 100 floors best results from watch are mabe 80-85 floors.
Crap not working

This is a piece of junk that claims to handle counting "Floor Climb" from Baromati but it doesn't work at all to count floors, it reads empty mess is slightly sharper if I always calibrate before I start than if I calibrate that before i start consider it very imprecise. I have noticed that if I stop at each floor and walk around it is slightly better which indicates that the Barometer is taking a very long time to respond to the air pressure change that the "Floor Climb" uses.
So you need to wait for the barometer to read. It's of course a useless trick if that's the case, because the purpose is to get a good workout and get your heart rate up, which doesn't happen if you need to stop on every hill to get a slightly better count. I am walking 10 floors up and down a total of 100 floors with a brand new watch that I replaced because I thought it was broken and the watch is counting at most 80-85 floors IF I STOP AT EACH FLOOR AND WALK AROUND but if I walk briskly to get the pulse up well, the accuracy of the watch is at best 60%.

You have a different production than the two Garmin Venu 3S watches that I have tested, I replaced the watch and got a new one because I thought it was broken, but it was just as bad. If you are getting a reading that is correct, I think you are one of the few that I know of at least that has that story to tell. Maybe the watches are made in different places with different quality sensors.

The survey above says that 89% have a watch that doesn't count right. My two count horribly wrong.

My Garmin Venu 3 watch counts very wrong. Don't tell me that the watch needs to be cleaned, that's not the problem. I've done everything the service people tell me.
If I'm inside a house and do a "Floor Climb" and Calibrate the watch manually or GPS, the accuracy is never good. Sometimes it counts nothing. If I Calibrate for Baromat and immediately go to Floor Climb, it's skewed, but I walk down 2 floors and back up to the same place. When I do 150 floors up and down, the watch is usually like this with 100 floors. The watch is completely useless if I don't Calibrate immediately before.
The watch only seems to count correctly if I stop at each floor and walk around, which suggests that the Baromats' response time is simply very slow and the watch is not capable of counting floors if you walk briskly up and down two floors 150 times. At best, the watch counts 60%.
